Description and Introduction

FAST REGISTERED SPEED Tsu,Tso 8-MACROCELL The **P85C224-66** is a high-performance microcontroller developed by **HARRIS Semiconductor**, designed for embedded control applications requiring robust processing capabilities and efficient power management. As part of the 80C51 microcontroller family, it operates at a clock speed of **12 MHz**, ensuring reliable performance for real-time computing tasks.  

This component features **4 KB of on-chip ROM**, **128 bytes of RAM**, and a versatile **8-bit CPU architecture**, making it suitable for industrial automation, automotive systems, and consumer electronics. Its **low-power CMOS technology** enhances energy efficiency, while its **extended temperature range** ensures stability in demanding environments.  

The **P85C224-66** supports multiple I/O ports, timers, and serial communication interfaces, providing flexibility for diverse interfacing requirements. Additionally, its **66 ns access time** facilitates rapid data processing, improving system responsiveness.  

Engineers favor this microcontroller for its **durability, ease of integration, and backward compatibility** with the 8051 instruction set. Whether used in legacy systems or modern embedded designs, the **P85C224-66** remains a dependable choice for developers seeking a balance of performance and reliability.  

With its proven architecture and industry-standard features, this component continues to serve as a foundational element in microcontroller-based applications.

Application Scenarios & Design Considerations

FAST REGISTERED SPEED Tsu,Tso 8-MACROCELL

Alternative Part Number

  • 82C54 --: Programmable interval timer from the same Intel peripheral family, commonly used as a functional substitute in legacy designs.
  • 8254 --: Industry-standard programmable interval timer compatible with the 82C54 architecture, widely available as a replacement.
  • 82C54-2 --: Higher-speed variant of the 82C54 timer with the same pinout and function, suitable for drop-in replacement.
  • IS61C256AH-15N --: 32K x 8 high-speed asynchronous SRAM with similar 5V TTL interface and access time class, commonly used as a drop-in replacement for 8-bit SRAM devices.
  • CY7C199-15PC --: 32K x 8 asynchronous SRAM with comparable speed and pinout, widely available and electrically compatible with standard 8-bit SRAM sockets.
  • AS7C256-15PC --: 32K x 8 low-power CMOS SRAM offering similar timing and interface characteristics, suitable as a functional substitute in legacy designs.
  • IS82C54-10 --: Harris programmable timer/counter devices were rebranded under Intersil; this is a functionally equivalent CMOS timer with similar pinout and timing, widely available as a drop-in replacement.
  • 82C54-2 --: Renesas (formerly Intersil/GE) continues the 82C54 programmable interval timer family that Harris second-sourced; same function and package options, good availability.
  • CP82C54-10 --: Another 82C54-family programmable timer from the same lineage, offering equivalent counter/timer functionality and a different naming prefix for easy distinction from the Harris original.
